The Internal Revenue Service has provided additional expanded penalty relief to taxpayers whose 2018 federal income tax withholding and estimated tax payments fell short of their total tax liability for the year. The IRS is lowering to 80 percent the threshold required to qualify for this relief. Under the relief originally announced January 16, the threshold was 85 percent. The usual percentage threshold is 90 percent to avoid a penalty. “We heard the concerns from taxpayers and others in the tax community, and we made this adjustment in an effort to be responsive to a unique scenario this year,” said IRS Commissioner Chuck Rettig. “The expanded penalty waiver will help many taxpayers who didn’t have enough tax withheld. We continue to urge people to check their withholding again this year to make sure they are having the right amount of tax withheld for 2019.” This means that the IRS is now waiving the estimated tax penalty for any taxpayer who paid at least 80 percent of their total tax liability during the year through federal income tax withholding, quarterly estimated tax payments or a combination of the two. Today’s revised waiver computation will be integrated into commercially-available tax software and reflected in the forthcoming revision of the instructions for Form 2210, Underpayment of Estimated Tax by Individuals, Estates, and Trusts. Taxpayers who have already filed for tax year 2018 but qualify for this expanded relief may claim a refund by filing Form 843, Claim for Refund and Request for Abatement and include the statement “80% Waiver of estimated tax penalty” on Line 7. This form cannot be filed electronically. Today’s expanded relief will help many taxpayers who owe tax when they file, including taxpayers who did not properly adjust their withholding and estimated tax payments to reflect an array of changes under the Tax Cuts and Jobs Act (TCJA), the far-reaching tax reform law enacted in December 2017. For waiver purposes only, this relief lowers the 90 percent threshold to 80 percent. This means that a taxpayer will not owe a penalty if they paid at least 80 percent of their total 2018 tax liability. If the taxpayer paid less than 80 percent, then they are not eligible for the waiver and the penalty will be calculated as it normally would be, using the 90 percent threshold.
